I have bought Ethereum for four different wallet for about two months plus the growth was very very slow so I decided to convert one my exchange Ethereum that I bought to Bitcoin and to see the differences guys there is very big different. I convert it with the Ethereum value was equal to $10.85 and I convert it, it was about 0.00015 in Bitcoin and Bitcoin was $66+k and when Bitcoin climbed to $71,799 and when I sold it it came out as $13.30 or there about though the exchange didn't show the dollar value and only on the local currency.
And the $10 was there in the Ethereum for months without changed and it only Change within 4 days of my converting. So I will not advise to invest in Ethereum for now until the congestion has reduced. And if you are looking for a promising altcoins to invest then try Eloncoin.
